To all whom t may concern. V

Be it known that l.; RICHARD, L. @Lairiir'rs, a citizen of the UnitedStates, residing at Irvington, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements in SolderlessCan-Sealing Apparatus, of which the fol lowing is a specification. i

This invention relates to the art of sealing receptacles made of tin yorlilre sheet material, and` has particular reference to the sealing ofcans without solder.

i'linong the objects of the invention ist() produce a machine ormechanism for sealing` metal cans niuclimore rapidly and moreefficientiy than heretofore has been practised and at the same time to`reduce to a minimum the percentage offailures to make proper seal.

i: nother obJect of the invention is to provide an apparatus of thecharacter set forth including a can seal contact member or pad which isrelatively` stationaryand whereby the seal is held reliably in properposition for and during` the sealing action.

itt further object of the invention is to provide means for adapting themechanism to and for operation by various types of standard motors andwith means carried by the motor casing for holding the aforesaid sealpad or contact member stationary.

A still further object of the invention is to liiovide in a more precisemanner than heretofore for the adjustment of such parte of the mechanismas require delicate adjustment for the effective sealing action thereof.

`With the foregoing and otherobjects in view the invention consists inthe arrangement and combination of parts hereinafter described andclaimed, and while the invention is not restricted to the exact detailsof construction disclosed or suggested herein. still for die purpose ofillustrating a practical embodiment thereof reference is had to theaccompanying drawings, in which like reference characters` designate thesame parts in the several views, and in which- Figure 1 is a verticalsect-ion of a preferred embodiment of the invention shown as applied toone well known type of motor from which the rotating parts of themechanism may be driven.

Figs. 6, 7,`and 8 are diagrams indicating `progressive steps in thesealing action.

Fig, 9 is a horizontal detailon the line 9--9of Fig. 1. y

Figs.` 10 and `11 are details described below.

Referring now more` specifically to the drawings, l show a motor Mhaving a casing 10 and a bearing hubll, the latter being arranged at thebottom of the casing and at vone side of the axis of the motor shaft 12to which is fixed a pinion 13. Within `the hub 11 is arranged a thrustbearing ring 1li with relation to which is a companionring 15 fixed inany suitable manner to a sleeve or hollow shaft 16 projectingupward intothe motor` easing and to whose upper end is fixed a gear 17 meshing withsaid pinion 13. 'Vithin the motor casing is fixed vin any suitablemanner a bracket 18 to which is lsecured. by means preferably of aylefthand thread 19 and locking nut 20,1a stein 21 projecting downwardthrough said shaft 16. Upon the lower end of the stem is fixed a chuclror head 22 by any suitable means, preferably a lefty handed thread 23.Fitted transversely through the chuck 22 is a bar 24 held in place as bymeans of a screw 25. The innermost face ofthe bar isspaced from the ofthe'stcm and chuck.

lt will be understood that the stem is held stationary withv respect tolthe motor casing and that the shaft 16 is adapted for rotation at highspeed from the motor shaft 12. Fixed to the shaft 16and constituting aneX: tension thereof is a substantiallycylindrical head. 26, the meansfor securing' it to the shaft 16 being indicated as a coupling 27`having an internal thread 28 for connection to the "lower end of theshaft and having an external thread 29 `for cooperation with theinternal thread 30 tapped intothe upper end of the head, the extent ofthethread 30 being great enough to provide for any necessaryv y`adjustment axially between the shaft and the head.` The interior of thehead being .means f'fcmprising a member revolved va finishing member'for etl'ee f action.
